Background: For patients with gastric cancer, the pathway from primary care (PC) clinician to gastroenterologist to cancer specialist (medical oncologist or surgeons) is referral dependent. The impact of clinician connectedness on disparities in quality gastric cancer care, such as at National Cancer Institute-designated cancer centers (NCI-CC), remains underexplored. This study evaluated how clinician connectedness influences access to gastrectomy at NCI-CC.

Given the exponentially aging population and rising life expectancy in the United States, surgeons are facing a challenging frail population who may require surgery but may not qualify based on their general fitness. There is an urgent need for greater awareness of the importance of frailty measurement and the implementation of universal assessment of frail patients into clinical practice. Pairing risk stratification with stringent protocols for prehabilitation and minimally invasive surgery and appropriate enhanced recovery protocols could optimize and condition frail patients before, during, and immediately after surgery to mitigate postoperative complications and consequences on patient function and quality of life.

Objective: In this study we sought to evaluate whether disparate use of transcatheter aortic valve replacement (TAVR) among non-White patients has decreased over time, and if unequal access to TAVR is driven by unequal access to high-volume hospitals.

Methods: From 2013 to 2017, we used the State Inpatient Database across 8 states (Ariz, Colo, Fla, Md, NC, NM, Nev, Wash) to identify 51,232 Medicare beneficiaries who underwent TAVR versus surgical aortic valve replacement. Hospitals were categorized as low- (<50 per year), medium- (50-100 per year), or high-volume (>100 per year) according to total valve procedures (TAVR + surgical aortic valve replacement).

Background: Regional lymph node metastasis (RLNM) occurs infrequently in patients with soft tissue sarcoma (STS), although certain STS subtypes have a higher propensity for RLNM. The identification of RLNM has significant implications for staging and prognosis; however, the precise impact of node-positive disease on patient survival remains a topic of controversy. Although the benefits of sentinel lymph node biopsy (SLNB) are well documented in patients with melanoma and breast cancer, whether this procedure offers a benefit in STS is controversial.

Background: Limited data exist on safe discontinuation of antiprogrammed cell death protein 1 (PD-1) therapy in responding patients with advanced melanoma. The use of 18fluorodeoxyglucose (FDG)-PET/CT scan and tumor biopsy for assessment of active disease may be an effective predictive biomarker to guide such treatment decisions.

Methods: A retrospective study of 122 patients with advanced melanoma treated with anti-PD-1 monotherapy or anti-PD-1/anticytotoxic T-lymphocyte-associated protein 4 combination therapy at Georgetown Lombardi Comprehensive Cancer Center was conducted.

Background: Laparoscopic colectomy is considered the standard of care in colon cancer treatment when appropriate expertise is available. However, guidelines do not delineate what experience is required to implement this approach safely and effectively. This study aimed to establish a data-derived, hospital-level annual volume threshold for laparoscopic colectomy at which patient outcomes are optimized.

Background: Medicaid expansion (ME) under the Affordable Care Act has reduced the number of uninsured patients, although its preferential effects on vulnerable populations have been mixed. This study examined whether ME preferentially improved cardiac surgery use by insurance strata, race, and income level.

Methods: Non-elderly adults (aged 18-64 years) who underwent coronary artery bypass grafting, aortic valve replacement, mitral valve replacement, or mitral valve repair were identified in the State Inpatient Databases for 3 expansion states (Kentucky, New Jersey, and Maryland) and 2 non-expansion states (North Carolina and Florida) from 2012 to the third quarter of 2015.

Mistreatment has been documented as a negative factor in the learning environment for the past 30 y but little progress has been made to determine an effective way to significantly improve these interactions. Faculty may also be victims of a hostile work environment as well, although frequency has not been well-measured or reported. In fact, it may be difficult to identify and address mistreatment and hostility in the work place within the commonly established surgical culture.
